(TlNOSA.) 



Head 3; depth 2 ; eye 4*. D. VII-I, 21; A. II-I, 18. Body oblong 

 ovate, compressed, deep, the back elevated, but not arched. Profile gib- 

 bous from occiput forward to above eye, thence straight and steep at a 

 considerable angle to a point in front of nostrils, whence the snout again 

 projects at a strong angle. Outline of back nearly straight from occiput 

 to front of second dorsal, thence declining regularly to caudal peduncle. 

 Ventral outline nearly straight from lower jaw to origin of anal, the base 

 o'f which is placed at a similar angle to that of soft dorsal. Head large, 

 very deep, deeper than long, occipital ridge not sharp. Mouth large, the 

 broad maxillary reaching to opposite front of pupil. Lower jaw strong, 

 the chin projecting when mouth is closed. Teeth in upper jaw in a narrow 

 villiform band, with an outer series of larger, conical teeth, 6 to 8 in num- 

 ber on each side, subequal and regularly arranged. Lower jaw with a 

 single series of teeth similar to the larger teeth of upper jaw, a few smaller 

 teeth intermixed with them. No differentiated canine teeth. Villiform 

 teeth on vomer, palatines, and tongue. Gill rakers rather long, close-set, 

 i diameter of eye. Eye large, with a distinct adipose eyelid, its diameter 

 equal to that of the broad preorbital, which is wider than maxillary.
